In the Post Microwave Age, your push-button oven has been replaced by a push-button can. Just press the bottom of this insulated steel container, and a packet of compressed liquefied salt heats the soup to a steaming 130 degrees. Despite the Campbell's label, the can, R&D'd by SuperHappyBunny (www.superhappybunny.com), has yet to be licensed for commercial use. But SHB has plenty of cred: Its designers have worked for clients as big as General Motors and Nine Inch Nails, and they're currently busy with T-shirts for LA's trendy Ben Ryan Clothing. After that, the Bunnies aim to take the self-heating soup can off the back burner.
